A MINOR REFORM

Forcing a sparse minor

This paper addresses the following question for a given graph H : what is the minimum number f(H) such that every graph with average degree at least f(H) contains H as a minor? Due to connections with Hadwiger’s Conjecture, this question has been studied in depth when H is a complete graph. Kostochka and Thomason independently proved that f(Kt) = ct √ ln t. More generally, Myers and Thomason de...

Excluding a small minor

There are sixteen 3-connected graphs on eleven or fewer edges. For each of these graphs H we discuss the structure of graphs that do not contain a minor isomorphic to H.

The politics of malpractice have become so lawyer-centric that recognizing the availability of broader gains from trade in to...
